The tekmar Mixing Control 365 is a microprocessor-based control with a 120 Vac output for operating
a variable speed injection pump. A 4-20mA output is available for operating devices such as a 4-
20mA actuating motor, modulating gas valve, a mixing valve combination, or for operating a 4-20mA
motor drive for larger variable speed pumps. The variable speed pump or mixing valve regulates the
supply water temperature to a heating system based on the outdoor air temperature, and optionally,
the indoor air temperature. The system is shut down when there is no Heat Demand signal or when
the outdoor temperature is warm enough so that the system no longer requires heat (WWSD).
